What is Total Knee Replacement Surgery?
Total knee replacement surgery in Chennai is a highly effective orthopedic procedure where damaged cartilage and bone from the knee joint are removed and replaced with artificial implants made of metal and medical-grade plastic. These implants replicate natural joint movement, allowing smoother function and reduced pain.
This procedure is commonly recommended when conservative treatments like medication, physiotherapy, and injections fail to provide relief. With advanced total knee replacement treatment in Chennai, patients benefit from minimally invasive techniques, faster recovery, and long-lasting results.
When Do You Need Total Knee Replacement? (Symptoms & Warning Signs)
You may need total knee replacement surgery in Chennai if you experience:
- Persistent or Chronic Pain: Continuous knee pain that doesn’t improve with rest and may disturb sleep or daily activities.
- Severe Joint Stiffness: Difficulty in bending or straightening the knee, making movements like sitting or standing uncomfortable.
- Failed Non-Surgical Treatments: Medications, injections, or physiotherapy no longer provide effective relief from pain or stiffness.
- Reduced Mobility & Activity Limitations: Trouble walking, climbing stairs, or performing routine tasks due to limited joint function.
- Visible Deformity or Instability: Noticeable bowing of the knee or a feeling that the joint may give way while walking.

Types of Knee Replacement Surgery
At Sunway Medical Centre, different surgical options are available:
- Total Knee Replacement (TKR): This procedure involves replacing the entire knee joint with artificial components to restore function and eliminate pain. It is recommended for patients with severe arthritis or extensive joint damage affecting the whole knee.
- Partial Knee Replacement: Only the damaged portion of the knee is replaced while preserving the healthy bone and tissue. This option is ideal for patients with limited joint damage and allows for faster recovery and more natural knee movement.
- Revision Knee Replacement: This surgery is performed when a previous knee implant fails, wears out, or becomes loose over time. It is more complex than primary surgery and requires specialized expertise to restore stability and function.
- Bilateral Knee Replacement: Both knees are replaced either during the same surgery or in two separate procedures. It is suitable for patients with severe pain and damage in both knees, helping them regain balanced mobility and function.
Choosing the right type depends on the severity of damage and patient health condition.
Pre-Surgery Preparation
Proper preparation ensures better outcomes for total knee replacement surgery in Chennai:
- Medical & Physical Evaluation: A complete health check-up helps assess fitness for surgery and identify any risks beforehand.
- Prehabilitation: Performing strengthening exercises before surgery improves muscle support and speeds up post-surgery recovery.
- Home Preparation: Arrange for assistance, install safety supports, and create a comfortable recovery space at home.
- Infection Control: Any existing infections must be treated prior to surgery to reduce the risk of complications.
- Diet & Lifestyle: Maintain a healthy diet, stay active, and avoid smoking or alcohol to support better healing.
- Day Before Surgery: Follow fasting instructions and medication guidelines as advised by your doctor for a safe procedure.
Patients seeking affordable total knee replacement surgery in Chennai should also discuss financial planning and insurance coverage beforehand.
Total Knee Replacement Procedure (Step-by-Step)
The procedure typically involves:
- Preparation & Anesthesia: The patient is given general or spinal anesthesia to ensure a pain-free procedure. Vital signs are monitored continuously to maintain safety throughout the surgery.
- Incision: A carefully planned incision is made over the knee to access the joint. The size and placement of the incision depend on the surgical technique used.
- Exposure: The surgeon gently moves the muscles and tissues aside to clearly view the damaged knee joint. This step ensures precision during the procedure.
- Resurfacing the Femur & Tibia: Damaged cartilage and bone from the thigh bone (femur) and shin bone (tibia) are removed. The surfaces are then shaped to fit the artificial components accurately.
- Positioning the Prosthesis: Metal implants are securely fixed onto the prepared bone surfaces using specialized techniques. Proper alignment is crucial for natural movement and long-term success.
- Inserting the Spacer: A medical-grade plastic spacer is placed between the metal components. This allows smooth gliding of the joint and reduces friction during movement.
- Resurfacing the Patella: If necessary, the underside of the kneecap is resurfaced and fitted with a plastic component. This helps improve joint function and reduces pain.
- Testing the Joint: The surgeon checks the knee’s range of motion, stability, and alignment. Adjustments are made to ensure the joint moves naturally and functions properly.
- Closure: The incision is carefully closed using sutures or staples, and a sterile dressing is applied. The patient is then moved to recovery for monitoring and initial care.
With advanced total knee replacement treatment in Chennai, precision tools and robotic assistance may be used for better accuracy.
What to Expect During Surgery
Patients undergoing total knee replacement surgery in Chennai can expect:
- Duration: The surgery typically takes around 1.5 to 2 hours, depending on the complexity of the case and the patient’s condition. Advanced techniques help improve precision and reduce operative time.
- Hospital Stay: Most patients stay in the hospital for 3 to 5 days for monitoring and initial recovery. During this time, doctors ensure proper healing and begin basic rehabilitation.
- Immediate Post-Surgery: After surgery, patients are closely monitored and given pain management support. Early movement and physiotherapy are encouraged to promote faster recovery and prevent complications.
The medical team ensures patient comfort and safety throughout the process.
Recovery Timeline & Rehabilitation
Recovery is gradual and structured:
- Weeks 1–2: During the initial phase, the focus is on pain management and gentle movements. Patients begin basic exercises and may start walking short distances with support.
- Weeks 2–6: Patients gradually increase mobility with the help of walkers or canes while continuing physiotherapy. Strength and flexibility begin to improve during this stage.
- Weeks 7–11: This phase focuses on strengthening the muscles around the knee and improving joint stability. Patients experience better movement and reduced discomfort.
- Months 3–12: Most patients return to normal daily activities with minimal restrictions. Continued exercise and follow-ups help achieve full recovery and long-term joint function.
Patients undergoing total knee replacement in Chennai benefit from personalized rehabilitation programs that speed up recovery.
Postoperative Care & Lifestyle Tips
Proper care after total knee replacement surgery in Chennai is essential:
- Wound Care: Keep the surgical incision clean and dry to prevent infection. Follow your doctor’s instructions for dressing changes and monitor for any signs of redness or discharge.
- Pain Management: Take prescribed medications as directed to control pain and inflammation. Proper pain management helps improve comfort and supports early mobility.
- Mobility: Gradually increase movement with the help of assistive devices like walkers or canes. Early mobility is crucial for preventing stiffness and improving circulation.
- Ice & Elevation: Apply ice packs and keep the leg elevated to reduce swelling and discomfort. This also helps in faster healing during the initial recovery phase.
- Daily Routine: Maintain a balanced daily routine with regular movement and adequate rest. Avoid prolonged sitting or standing to prevent strain on the knee.
- Exercise: Continue physiotherapy exercises consistently to regain strength, flexibility, and joint function. Regular exercise is key to a successful recovery.
- Weight Management: Maintain a healthy body weight to reduce stress on the new knee joint. Proper weight control enhances the longevity of the implant.
- Follow-ups: Attend all scheduled doctor visits to monitor healing and progress. Regular check-ups help detect and address any complications early.
These steps ensure long-term success and implant durability.
Benefits of Total Knee Replacement
The benefits of total knee replacement surgery in Chennai include:
- Significant Pain Relief: One of the biggest advantages is long-term relief from chronic knee pain caused by arthritis or injury. Most patients experience a dramatic reduction in discomfort after recovery.
- Improved Mobility and Flexibility: The procedure restores smoother joint movement, making it easier to walk, climb stairs, and perform daily activities. Patients regain better flexibility compared to their pre-surgery condition.
- Correction of Deformities: Knee replacement helps correct alignment issues such as bowing or joint deformities. This improves posture and ensures even weight distribution across the joint.
- Enhanced Joint Stability: The artificial implants provide better support and stability to the knee joint. This reduces the risk of falls and increases confidence while moving.
- Better Quality of Life: With reduced pain and improved mobility, patients can return to an active and independent lifestyle. It also positively impacts mental well-being and overall happiness.
Patients often return to normal activities with renewed confidence and independence.
Risks & Complications
Like any surgery, there are potential risks:
- Infection: Infections can occur at the incision site or around the implant, though they are relatively rare. Proper hygiene, antibiotics, and post-surgical care significantly reduce this risk.
- Blood Clots (DVT or Pulmonary Embolism): Blood clots may form in the leg veins after surgery and can become serious if they travel to the lungs. Early movement, medications, and compression devices help prevent this complication.
- Stiffness or Limited Motion: Some patients may experience reduced flexibility or difficulty bending the knee after surgery. Regular physiotherapy and exercises are essential to restore full range of motion.
- Implant Loosening or Failure: Over time, the artificial joint may wear out or loosen, especially with excessive stress or activity. In such cases, revision surgery may be required to restore function.
- Persistent Pain: While most patients experience pain relief, a small number may continue to have discomfort after surgery. This can often be managed with proper rehabilitation and medical support.
- Nerve Damage or Numbness: There is a slight risk of nerve injury during surgery, which may cause numbness or weakness around the knee. This is usually temporary but may rarely be long-lasting.
- Rare Fractures: Fractures around the implant can occur during or after surgery, especially in patients with weak bones. Careful surgical technique and post-operative precautions help minimize this risk.
Choosing experienced surgeons at Sunway Medical Centre minimizes these risks significantly.
